Ukhetho oluchanekileyo lweeNdlela ezimbini zeHydraulic zokutshixa kunye neeValufa zeBalance kwiiNkqubo zeHydraulic
2024-02-20Iimpawu zesakhiwo seendlela ezimbini zokutshixa i-hydraulic:
Indlela ezimbini yokutshixa ihydraulic ziivalvu ezimbini ezilawulwa ngolwelo lwendlela enye ezisetyenziswa kunye. Ngokuqhelekileyo isetyenziswe kwiisilinda ze-hydraulic ezithwala imithwalo okanye iisekethe ze-oyile yemoto ukukhusela i-cylinder ye-hydraulic okanye i-motor ukuba ihambe phantsi phantsi kwesenzo sezinto ezinzima. Xa isenzo sifunekayo, i-oyile kufuneka inikezelwe kwenye isekethe, kwaye i-valve yendlela enye kufuneka ivulwe nge-oyile yolawulo lwangaphakathi ukuvumela i-oyile yesekethe ukuba Kuphela xa idityanisiwe inokuthi i-cylinder ye-hydraulic okanye i-motor isebenze.
Ngenxa yesakhiwo somatshini ngokwawo, ngexesha lokuhamba kwe-cylinder ye-hydraulic, ubunzima obufayo bomthwalo buhlala bubangela ukulahlekelwa ngokukhawuleza koxinzelelo kwigumbi eliphambili lokusebenza, okubangela ukuba kubekho i-vacuum.
Le meko ihlala isenzeka kolu matshini lulandelayo lulandelayo:
①Isilinda yeoli ebekwe ngokuthe nkqo kumshicilelo we-hydraulic wekholamu emine;
② Isilinda sokungunda esingaphezulu koomatshini bokwenza izitena;
③Swing cylinder koomatshini bokwakha;
④I-winch motor ye-hydraulic crane;
Esona sitshixo sehydraulic esixhaphake kakhulu sisivalo esipakishwe ngendlela enye. Xa into enzima iwela ngobunzima bayo, ukuba icala leoyile yokulawula ayizaliswanga ngexesha, ivacuum iya kuveliswa kwicala le-B, okubangela ukuba ipiston yolawulo ihlehle phantsi kwesenzo sentwasahlobo, ibangele ivalve yendlela enye. ukuya Ivalve ivaliwe, kwaye ke unikezelo lwe-oyile luyaqhubeka ukwandisa uxinzelelo kwigumbi lokusebenza kwaye emva koko ivalve yendlela enye ivuliwe. Izenzo ezinjalo zokuvula rhoqo kunye nokuvala ziya kubangela ukuba umthwalo uqhubele phambili ngexesha lenkqubo yokuwa, okukhokelela kwimpembelelo enkulu kunye nokungcangcazela. Ngoko ke, ukutshixa kweendlela ezimbini ze-hydraulic ngokuqhelekileyo akukhuthazwa kwisantya esiphezulu kunye neemeko zomthwalo onzima, kodwa zisetyenziswa ngokuqhelekileyo. Ifanelekile kwiilophu ezivaliweyo kunye nexesha elide lokuxhasa kunye nesantya esisezantsi sokuhamba.
2. Iimpawu zesakhiwo sevalve yokulinganisa:
Ivalve yebhalansi, ekwabizwa ngokuba sisitshixo somda wesantya, yivalve elawulwa ngaphandle yokuvuza yangaphakathi yolandelelwano lwendlela enye. Ibandakanya ivalve yendlela enye kunye nevalve yolandelelwano esetyenziswa kunye. Kwisekethe ye-hydraulic, inokuthintela ioyile kwi-hydraulic cylinder okanye i-motor oil circuit. Ulwelo luthintela i-cylinder yehydraulic okanye imotor ekutyibilikeni ezantsi ngenxa yobunzima bomthwalo, kwaye isebenza njengesitshixo ngeli xesha.
Xa i-cylinder ye-hydraulic okanye i-motor kufuneka ihambe, i-fluid idluliselwa kwelinye isiphaluka seoli, kwaye ngelo xesha, i-oil circuit yangaphakathi ye-valve yokulinganisa ilawula ukuvulwa kwe-valve yokulandelelana ukudibanisa isiphaluka kwaye iqonde ukuhamba kwayo. Ekubeni ukwakhiwa kwevalve yolandelelwano ngokwalo yahlukile kuleyo yeendlela ezimbini zokutshixa i-hydraulic, uxinzelelo oluthile lwasemva lusekwe ngokubanzi kwisekethe yokusebenza xa usebenza, ukuze umsebenzi ophambili we-hydraulic cylinder okanye i-motor ayiyi kuvelisa uxinzelelo olubi. ngenxa yobunzima bayo kunye ne-overspeed sliding, ngoko ke akukho ntshukumo iya phambili iya kwenzeka. Ukothuka kunye nokungcangcazela njengesitshixo se-hydraulic esineendlela ezimbini.
Ngoko ke, iivalve zokulinganisa zisetyenziswa ngokubanzi kwiisekethe ezinesantya esiphezulu kunye nomthwalo onzima kunye neemfuno ezithile zokuzinza kwesantya.
3. Ukuthelekiswa kweevalvu ezimbini:
Ngokuthelekisa, sinokubona ukuba xa usebenzisa iivalve ezimbini, kufuneka zikhethwe ngokuguquguqukayo ngokweemfuno zezixhobo, kwaye kufuneka zisetyenziswe kunye xa kuyimfuneko.
4.Idityaniswe nohlalutyo lwesakhiwo sevalve yokulinganisa kunye ne-hydraulic lock yeendlela ezimbini, sincoma:
① Kwimeko yesantya esiphantsi kunye nomthwalo okhanyayo kunye neemfuno zokuzinza kwesantya esisezantsi, ukuze kuncitshiswe iindleko, i-lock-way hydraulic lock ingasetyenziswa njengesitshixo sesiphaluka.
② Kwiimeko zesantya esiphezulu kunye nomthwalo onzima, ngakumbi apho iimfuno zokuzinza kwesantya esiphezulu zifunekayo, i-valve yokulinganisa kufuneka isetyenziswe njengenxalenye yokutshixa. Musa ukulandela ngokumfamekileyo ukunciphisa iindleko kwaye usebenzise isitshixo se-hydraulic lock, kungenjalo kuya kubangela ilahleko enkulu.
